Why am I getting fewer ProvenExpert reviews than the customers I invited?

The ProvenExpert help pages give 4 common reasons. The first to rule out: An invitation email can land in a customer's spam folder, so the customer may never see it.

What causes it?

  1. An invitation email can land in a customer's spam folder, so the customer may never see it.

  3. A customer can review you only once per survey with the same email address, so inviting a past reviewer to the same survey can bring no new review.

  4. Customers who reach a survey without an email invitation are asked to confirm their review from an email, which adds a step before the review is done.

How does ProvenExpert work with Feder?

  • Connect ProvenExpert to Feder and it joins your Experience apps.
  • When you connect ProvenExpert, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.

Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.

See whether you can trust the numbers in ProvenExpert, one of your Experience apps. Feder only reads. It never changes anything in ProvenExpert.
